DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0031] Specifically, Figure 1 As shown, in the embodiment of the present application, there is provided a synthetic leather dynamic laminating device, which specifically includes: a first roller 100, a second roller 200, a first heating device 300, a second heating device 400 and a diversion device 500, specifically:

[0032] A release paper is placed on the first roller 100, and the release paper is advanced by the rotation of the roller on the first roller 100. A second roller 200 is arranged on one side of the first roller 100, and one end of the second roller 200 is located on the first roller 100. A pressing wheel 210 is installed on the second roller 200, and a base cloth is placed on the second roller 200. The base cloth is driven by the pressing wheel 210 to fit with the release paper to form synthetic leather, and the synthetic leather moves on the first roller 100.

[0033] Before the release paper and the base fabric are combined, a coating head 110 is provided on the release paper. The coating head 110 coats glue on the side of the release paper facing the base fabric to combine the base fabric and the release paper to form synthetic leather.

[0034] After the synthetic leather is combined, it is necessary to perform high temperature treatment on the synthetic leather. The high temperature treatment is performed by the first heating device 300 and the second heating device 400. Specifically, the following steps are performed:

[0035] In the present application, the first heating device 300 is connected to the first roller 100, and a pressing piece 310 and a heating device 320 are provided on the first heating device 300. The pressing piece 310 presses the synthetic leather to facilitate the heating device 320 to heat the synthetic leather. The pressing piece 310 is installed on the first roller 100 through a support frame. The pressing piece 310 includes a plurality of pressing blocks 311 and a pressing rod 312. The pressing rod 312 is installed on the first heating device 300, and the pressing rod 312 is arranged in the moving direction of the synthetic leather. A plurality of pressing blocks 311 are arranged on the pressing rod 312 toward one end of the synthetic leather. The plurality of pressing blocks 311 are movably connected to the pressing rod 312, and the plurality of pressing blocks 311 press the synthetic leather by the gravity of the pressing blocks 311 themselves. The pressing pieces 310 are arranged on both sides of the first heating device 300, so that the heating device 320 is located between the two pressing pieces 310.

[0036] In the above, the pressing block 311 slightly squeezes the synthetic leather in the present application to avoid the occurrence of pulp seepage and floating in the present application.

[0037] Preferably, in the present application, a telescopic motor 531 is further provided on the pressing rod 312 , and the pressing rod 312 in the present application is controlled by the telescopic motor 531 , so as to facilitate adjustment of the pressing force of the pressing block 311 on the synthetic leather.

[0038] Preferably, in the present application, the pressing block 311 is detachably connected to the pressing rod 312 to facilitate the adjustment of the pressure on the synthetic leather.

[0039] In the first heating device 300, the heating equipment 320 is a plurality of heating elements 321 and a temperature detector 322. The plurality of heating elements 321 are arranged in a rectangular shape in the first heating device 300, which can heat the synthetic leather evenly and avoid uneven heating of some parts of the synthetic leather, which may cause quality problems.

[0040] The heating element 321 is specifically located at the bottom or top of the first roller 100 . In the present application, the heating element 321 is preferably located at the top to facilitate heating of the synthetic leather.

[0041] In the embodiment of the present application, the heating element 321 is more preferably disposed at the bottom and the top of the first roller 100, so that the heated parts of the synthetic leather are more uniform.

[0042] The heating element 321 preheats the synthetic leather, and the heating temperature is stepped heating, the heating temperature range is 90-110 degrees Celsius, and the stepped heating is heating along the movement direction of the synthetic leather, specifically:

[0043] like Figure 2-Figure 3As shown, in the embodiment of the present application, the heating elements 321 are laid out in a long strip along the direction of the synthetic leather, and the heat released by each heating element 321 is fixed, so that on the long strip heating element 321, one end is in a heating range of 90 degrees Celsius, and the other end is in a heating range of 110 degrees Celsius. The heating temperature in the middle part is increased by 5 degrees every time to form each heating area, so that the synthetic leather is heated in a step-by-step manner.

[0044] During the heating process, the temperature of the synthetic leather needs to be controlled at all times to avoid the temperature being too high or too low. To avoid this situation, the temperature detector 322 in the present application detects the surface temperature of the synthetic leather to control the heating unit in each area to adjust the temperature.

[0045] In the second heating device 400, the heater 410 is located above the synthetic leather, and the heater 410 performs secondary heating on the synthetic leather. The temperature range of the heater 410 for the synthetic leather is 110-145 degrees Celsius, and the heater 410 performs step gradient heating on the synthetic leather.

[0046] In the present application, the heating stage of the heater 410 for the second heating is the same as the heating stage of the heater 410 for the first heating, and will not be described in detail here.

[0047] In the second heating, a temperature detector 322 is also provided. The temperature detector 322 detects the temperature range of the second heating, thereby controlling the temperature range of the synthetic leather.

[0048] The control method is the same as the temperature control of the first heating.

[0049] After the synthetic leather is heated for the second time, it enters the cutting device 600, which can cut the synthetic leather into sections to organize the synthetic leather.

[0050] A detection device 610 is also provided on the cutting device 600. The detection device 610 can detect the penetration degree of the segmented synthetic leather and mark the segmented synthetic leather, so that the synthetic leather is divided into qualified synthetic leather and unqualified synthetic leather.

[0051] When the synthetic leather shows obvious penetration, it is an unqualified product. When the synthetic leather does not show obvious penetration, it is a qualified product. At this time, the synthetic leather can be marked to record whether it is qualified.

[0052] After the synthetic leather is marked, it is necessary to divert the synthetic leather. A diverting device 500 is provided. Figure 2 and Figure 4As shown, the diverter device 500 includes a diverter plate 530, a first channel 510, and a second channel 520. The diverter plate 530 is provided with a motor 531 and a steering roller 532. The steering roller 532 is connected to the output end of the motor 531. The motor 531 controls the rotation of the steering roller 532 to divert the synthetic leather, so that the qualified synthetic leather enters the first channel 510, and the unqualified synthetic leather enters the second channel 520.

[0053] The motor 531 is a servo motor 531 .

[0054] A plurality of steering rollers 532 are provided, and the installation directions of the plurality of steering rollers 532 are all consistent. The plurality of steering rollers 532 are all driven to steer by the motor 531 .
